This is a new, unused item that has been stored in a warehouse for a long time. Length: Approximately 44.5cm Bead diameter: Approximately 1cm Asking price: ¥7000 The clasp is magnetic. The magnet is strong, as it snaps right back together as shown in the last photo, even when separated. It has a substantial weight. It's a lovely necklace and I think it's a great deal.
